A group of adventurers journey deep into the South American jungle in search of ancient Incan treasure. A beautiful woman, brought to their camp by hired bearers, has come to join her husband, a newer member of the group, who was recently killed by hostile natives. As the months pass, jealousies and tempers flare as fights break out over the woman. The Incan treasure is eventually found but the treasure-seekers, now united by a common enemy, are about to be attacked by hordes of fierce natives armed with bows and poisoned arrows.
